JOHN W. BARNABD, OF UNION CITY, TENNESSEE.

HARROW.

Application filed February 6, 1923. Serial No.'617,323.

To all whom 'if may concern.'

Be it known that I, JOHN W. BARNARD, a citizen of the United States, residing` at kUnion City, in the county of Obion and State of Tennessee, have invented certain new and useful `Improvements in Harrows; and l do hereby declare the following to be a full.` clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invent-ion has relation to a farm implement and is designed particularly to simplify and cheapen the harrow disclosed in Patent No. 1,140,238, granted me on the 18th day of May, 1915.

In accordance with the present invention, the number of parts is materially reduced, the structure simplilied and an implement provided which is readily adjustable to meet varying conditions of work and soil.

Other objects and advantages will be apparent and suggest themselves as the nature f of the invention is understood.

While the drawings illustrate an embodiment of thev invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may 'be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure 1 is a top plan view of a harrow embodying the invention,

Figure 2 is a front view thereof,

Figure 3 is a side elevation,

Figure i is a perspective view of the innermost harrow bars which are separated but arranged in the relative position which they will assume when assembled, and

Figure 5 is a detail view in perspective of one of the side sections.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

yllhe harrow illustrated is of the general type disclosed in my previous patent herein identified and is substantially of V-form, the several bars converging forwardly. In the preferable construction of the harrow, metal bars are employed as portions there of may be bent and thereby obviate the provision of a multiplicity of parts. The metal bars employed may be of any cross sectional outline and of any preferred size. The harrow comprises similar parts or sections which are disposed upon opposite sides of a medial line, the bars comprising each of the sections being disposed in parallel relation. The inner and rearmost bars 1 converge forwardly and each has an upward and inward extension 2 at its forward end and a similar extension 3 at its rear end and these extensions are adapted to overlap at their upper ends to form front and rear arches which are adjustable to admit of lateral adjustment of the bars 1, whereby their rear ends may be spread more or less,

or the bars as a whole may be spaced apart l a greater or less distance as required. The extensions 2 and 3 4constitute arch elements which overlap at their upper ends and are adapted to be secured in the required adjusted position by means of bolts 4 or other analogous fastening means. f

The similar side sections comprise outer members 5 and inner members 6. These members 5 and 6 are disposed in parallel relation with each other and with the ad- -with teeth 10 which may be of any construction or make, depending upon the particular work for which the implement is designed, whereby the same may be used either as a harrow or cultivator. Handlebars 11 areA secured at their lower ends Vto the forward portion of the side sections and braces 12 are adapted to connect upper rear portions of the handlebars with either the Chains 13 connect the Y bars 1 or the bars 5. handlebars 11 with the rear end of the bars 1 to admit of proper control thereof as may be required.

Referring more particularly to Figure 1 of the drawings, it is observed that the implement presents the appearance of three in one when the different parts are assembled,

the side sections constituting two ofV the parts and the middle section the third part. Short crossbars 14 are clipped or otherwise end into working position.

secured to the longitudinal portion 8 of the side sections and extend inwardly and receive teeth 10 which operate on the ground in the space formed between the forward ends of the side sections. The cross bar 14 are located in the rear of the draft chains l5 and the teeth applied thereto are removable to admit of the implement being used solely as a cultivator.

The teeth 10 are double pointed and are reversible to bring either point into operative position accordingly as the implement is to be used as a harrow or as acultivator. One end of the teeth is straight and of diamond shape and the opposite end is spread and curved to provide a cultivator tooth and, as stated, the teeth are reversible to bring either Clips 16 secure the teeth of' the supporting bars and admit of the teeth being adjusted vertically or reversed as required. Each oi' the side sections is preferably formed oia a single bar bent into the shape substantially as shown, thereby obviating the yformation of joints, and stay pieces 17 may supplement the action of the liller blocks 9 in maintaining the bars 5 and 6 in determinate spaced relation.

What is claimed is:

l. In an implement of the character specied, oppositely disposed toothed bars having integral extensions at opposite ends adapted when assembled to torni front and rear arches.

2. In an implement of the character spec-- ilied, oppositelyvdisposed toothed bars having integral extensions at opposite ends adapted when assembled to form front and rear arches, which are adjustable to admit of the bars being spaced apart a greater or less distance, and means for securin the upper overlapping ends of the arche elements to retain them and the bars in the required adjusted position.

3. An implement of the character specilied comprising inner rear bars forwardly converging and provided at opposite ends with upwardly extending arch elements which are adapted to be adjustably connected, .forwardly converging side sections hingedly connected to the inner bars, each section comprising inner and outer members and a connection uniting said members at their forward ends, said members and connection constituting parts of a single bar,- a iiller secured between the rear ends of the members, handlebars attached at their lower ends forward portions of the side sections, braces between the handlebars and members, and connecting chains between the` landle bars and the rear ends of the said inner bars.

4.. In an implement of the character specilied, oppositely disposed bars having integral extensions at opposite ends adapted when assembled to form front and rear arches, which are adjustable to admit of the bars being spaced apart a greater or less distance, and means for securing the upper overlapping ends of the arched elements to retain them and the bars in the required adjusted position. Y

In testimony whereof I aiiix my signature in presence of a witness.
